What is a  Transformer?

Transformer Definition

A transformer is a passive device that transfers electrical energy from one circuit to another using electromagnetic induction.

Transformer Parts And Construction

• Primary Winding of Transformer

• Magnetic Core of Transformer

• Secondary Winding of Transformer

Working Principle

The working principle of a transformer involves mutual induction between coils to transfer electrical energy.

Core Function

The core of a transformer provides a path with low reluctance, essential for efficient flux linkage between the windings.

Voltage Conversion

Depending on the turns ratio between the primary and secondary windings, a transformer can either step up or step down the voltage.

• If the primary coil has more turns than the secondary coil, the voltage decreases, known as step down.

• If the primary coil has fewer turns than the secondary coil, the voltage increases, known as step up.

Inrush Current Impact

The inrush current is the initial surge of electricity experienced when a transformer is switched on, affecting its immediate performance.
